Didn't realize that Greenies and rawhide were such a sensitive topic on this forum LOL. I was trying to suggest products that are not so hard that they will crack dogs back teeth. I got the information from a vets website, I didn't save the website information. Quite a few vet dental surgeons say that bones and horns and hard nylabones are not safe for dogs that chew hard.
1)Where do you get your information from that Greenies Grain free are so terrible- Here is the ingredient list:
Dried chickpeas, gelatin, glycerin, powdered cellulose, dried potato, water, lecithin, potato protein, natural poultry flavor, minerals (dicalcium phosphate, calcium carbonate, potassium chloride, magnesium amino acid chelate, zinc amino acid chelate, iron amino acid chelate, copper amino acid chelate, manganese amino acid chelate, potassium iodide), choline chloride, dried apple pomace, fruit juice color, vitamins ( dl-alpha tocopherol acetate [source of vitamin E], vitamin B12 supplement, d-calcium pantothenate [vitamin B5], niacin supplement, vitamin A supplement, riboflavin supplement [vitamin B2], vitamin D3 supplement, biotin, pyridoxine hydrochloride [vitamin B6], thiamine mononitrate [vitamin B1], folic acid), turmeric color.
2) With respect to C.E.T. rawhide, I wouldn't feed it to my dog since I don't want to have to supervise her while chewing it so that she doesn't swallow it. I would just give my dog C.E.T. Veggiedent chews, or some other VOHC recommended chews which aren't rawhid.. Veggiedent chews ingredients are as follows (not grain free) :
Corn starch, glycerin, soy bean protein, rice flour, palatable agent, sorbitol, corn cob, water, potassium sorbate.
